Two men suspected of targeting the Skripals with novichok have denied being Russian agents or having anything to do with the poisoning.

Alexander Petrov and Ruslan Boshirov told Russia Today (RT) they were only in Salisbury on 3 March as tourists to visit the cathedral and nearby Stonehenge.

In their first interview since being named as suspects by the British government they said they were victims of a "fantastical coincidence" and would like an apology from the real poisoners.

The pair, who claimed they were not using pseudonyms, said their friends had told them to visit "this wonderful town, Salisbury, which has a famous cathedral and 123m spire, and is famous for its clock".

They said they wanted to go to Stonehenge but were prevented from doing so because there was "muddy slush everywhere" so they got wet and went back to London an hour after arriving, as there was an intermittent weekend train service.

Southwestern Railway confirmed to Sky News there were engineering works that weekend and no direct trains from London to Salisbury, so they would have had to change at Basingstoke.

They confirmed they were the two men shown in CCTV pictures issued by the Metropolitan Police, saying they owned the clothes they were pictured in and even bought their shoes in England.

Salisbury MP John Glen said these statements were not credible and what they said did not match UK intelligence.

He added he was delighted that the Russians were able to see "the world class attractions Salisbury has to offer".

A statement from English Heritage revealed Stonehenge - known as Old Sarum - was closed to the public from 1 March to 4 March this year because of the snow.

Delighted that Alexander Petrov and Ruslan Borishov were able to see the world-class attractions that #Salisbury has to offer. But very strange to come all this way for just two days while carrying Novichok in their luggage. (1/2)

Salisbury welcomes tourists from around the world and is very much open for business. But the Petrov/Borishov statements are not credible and don't match the widely accepted intelligence we have on these individuals. (2/2)

A Foreign Office spokesman said that the two men had been identified as the prime suspects and it was clear they were GRU officers who "used a devastatingly toxic, illegal chemical weapons on the streets of our country".

"We have repeatedly asked Russia to account for what happened in Salisbury in March," he added.

"Today - just as we have seen throughout - they have responded with obfuscation and lies."

British intelligence found the novichok was stored in a fake Nina Ricci perfume bottle, but the two suspects said that would be a ridiculous way for them to transport poison, which they denied having, as it would be "silly for decent lads" to have women's perfume.

Mr Boshirov said: "The customs are checking everything, they would have questions as to why men have women's perfume in their luggage. We didn't have it."

The pair said they had travelled to Europe quite a lot for holidays and for business.

They spent New Year's Eve in Switzerland and have been to Vienna, the pair said.

"We examine the market, look if there is something new - some biologically active additives, amino acids, vitamins, microelements," the two said.

"We pick up the most necessary, come here and decide how to deliver the new products from this market here."

Addressing CCTV pictures of both men passing through a gate at Gatwick Airport at exactly the same time, Mr Boshirov said: "We always go together through the same corridor and the same custom service officer or a policeman.

"One goes, the other waits. We went through the corridor together, we always [do it] together. How did it happen? It's better to ask them [UK police]."

The Russian embassy in the UK reacted as it has throughout the Skripal saga, by tweeting a picture of newspaper coverage of the Salisbury case, adding: "Insults and ultimatums do not qualify as questions.

"For its part, Russia has sent over 60 requests to UK, receiving no meaningful reply."
